Thimble is just over three feet tall, a slender-limbed warforged with dull silver eyes, burnished to a mottled gray finish that blends in well with the shadows.  He stalks around with restless energy when not working or carving, getting uncomfortably close to people.  He thinks nothing of getting on top of furniture to look people in the eyes, and may climb out a window if people are moving too closely down the stairs.  He likes to rest in uncomfortably small places.  His ghulra (the unique symbol every  warforged bears on their forehead) is like an inverted cup, somewhat resembling the thimble for which he is named.
